Abstract (en)
[origin: EP3282720A1] The present invention relates to the technical field of wireless communications. Particularly disclosed in embodiments of the present invention are a data transmission method and device addressing the problem in the prior art of packet loss resulting from that a UE cannot receive, when transmitting data, data simultaneously transmitted by other UEs in a D2D transmission process. The method of the embodiment of the present invention comprises: selecting, by a first terminal and from a first transmission resource pool of the first terminal, a first resource group to be transmitted by the first terminal; and configuring a second terminal group, such that each second terminal cannot transmit data to the first terminal via a first resource in the first resource group, thus addressing the problem of packet loss resulting from that the UE cannot receive, when transmitting data, the data simultaneously transmitted by other UEs, and further improving a transmission efficiency.
